RADIATOR-SHUTTEE.

Application filed December 26, 1918.

/ l1 /7/ w/m/n it may concern ie it known that l. (IL-(LES A. PIPEN-ruucx. a citizen of the l nited States. and a resident oi' the city ofthicagro. county of l'oolciaud State of lllinois, have invented certainnew and liadiator-Shutters. 01 is a specification.

l v invention relates to improvements in radiator shutters especiallyadapted (or use on automobiles. and has for its object the provision ofan improved construction of this character which is simple and ellective in use. andrapable of: economical manufacture.

Uther objects will appear hereinafter.

The invention consists in the conibinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings which the following iornnn g a part of. this specification, andin which,

Figure 1, is a sidevihw, shown partially in section, oi the hood of anautomobile equipped with a radiator shutter embodying the invention,

Fig. 6. an enlarged partial vertical section of the shutter shown inopen positionv and Fig. 7, a side view. on a reduced scale, of a shutterin open position.

The preferred form of construction. as illustrated in the drawings.comprises a suit able sheet metal frame 9 adapted to be secured to thefront of the radiator of an automobile and provided with flanges 9around the edges of the opening in said frame. The opening in the frame8 is arranged to he closed by means of a plurality. of shutter slats 10.each of said slats con sisting' of a strip of sheet metal somewhatlonger than the width of the opening in i'rame 8 and h'a ing'inwardlyturned ends or flanges 11 pivoted at 12 to the flanges 9 the sideso'l"'i"rame a.

turned ends or flanges -11 of the slats 1.0 are pivotally connected withreinfmnng links or bars 13 by.means of loose rivets ll, wherebysimultaneoi s operation of said shutters is insured and the same aregreatly reinforced- Eaeh of the slats .0 is 0rd vided ,at its freeorswinging edge witli an inwardly extending;- li'p or liahge l5, and thelower slat-s are provided with outwardly turned lips 16 at their pivotededges, forming spaces 17 adapted to receive lips is on upper slats, thuseiiiectinir a. perfect air seal at this point when the slats are closed,as indicated in Fig. The uppermost slat 10 is provided at its innerpivoted edge with a rounded portion l8 adapted to shed the rain when theshutter. is closed and a lip 19 contacting with the adjoining flange 9to effect a perfect seal when the shutter is closed. The lip 15 on thelowermost slat ll) engages over the flange 9 at the lower edge of framewhen the shutter is closed, to form a perfect seal. at this point. Endsor flanges 11 also over the side flanges 9, thus effecting a tight sealagainst the passage of air at all points when the shutter is closed.

The shutter is normally held in open position by means of a coiled.spring 20 mounted on a bolt 21 on the inner side of theuppermost shutter10, as shown. i flexible cable is connected with the free or. swingingedge of the uppermost shutter 10. is led thence over a guide roller 23,through the radiator 2% of the automobile and thence through the hood ofthe automobile to'a slotted bar liar 25 isprovided on its lower edgewith notches 26 adapted to engage a stop plate 27 mounted on the innerside of the dashboard 28 of the automhbile. said bar 27 sliding freelythrough said dashboard and said notches serving to lock the shutter inari ous positions of adjustment or completely closed. desired.

By this arrangement it will be observed that the shutter may be readilyclosed by simply pulling upon the bar and Locking; said bar in nydesired position of adjust ment. The shutter is opeeied merely byreleasing said bar. The specific form and ar ran'gement of parts is asimple and ellicient having greatstrength and durability in use. andcapable of c onomical manufacture. I

lVhile T have illustrated and descrilw'l the preferred form ofconstruction for a aye-same carrying my invention into effect, this iscapable of variation and modification Without departing from the spiritof the invention. I, therefore, do not Wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come Within the scope of the appendedclaims.

Having described my invention, what I claim as new and desire to secureby Letters Patent is I 1. In a shutter device for automobile radiators,the combination of a frame. a series of shutters pivotally mounted insaid frame, means connecting all of said shutters to operate in unisorua rod traversing said frame under one of said shutters, a coiled springmounted on said rod and connected with a corresponding shutterto holdsaid shutters normally open, and means for closing said shutters.

2. In a shutter device for automobile radiators, the combination of aframe, a seriesof horizontal shutters having their ends pivotallymounted in said frame, a rod traversing said trame under the uppermostof said. shutters co-axially with the pivots thereofl a coiled springmounted on said rod and bearing against the uppermost shutter arrangedto hold said shutters normally open,- and means for closing saidshutters.

3. lna shutter device for automobile ra diators, the combination of aframe, a series of shutters in which the upper edge of the top shutteris formed on a. radius substanters or holding them in intermediatepOsi'- tions.

l. A shutter device for automobile radiators the combination of a seriesof shuttors, and strips to operate them in unison, a spring attachedeoaxially with the end. hearings under the top shutter to hold all theshutters open, and means for closing; the shutters or holding them inintermediate positions.

5. A shutter device for automobile radiators, the combination of aframe, a series of shutters connected tooperate in unison, a springconcealed under the top shutter to hold all the shutters open, aflexible connection to one oi the shutters to close all the shutters.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses CHARLES A. PIPENHAGEN.
